At a Cannes Film Festival during the 1970s Cilla joined George Harrison, Ringo Starr, and glam-rock pop star Marc Bolan to attend a screening of the John Lennon-Yoko Ono experimental film Erection. She also holidayed with them on this trip aboard a yacht chartered by Ringo. "Photograph" was written on this trip - originally intended for Black to record - but Starr decided to record it himself. George Harrison also wrote two songs for Cilla - "The Light That Has Lighted The World" and "I'll Still Love You (When Every Song Is Sung)". The latter she recorded in 1974, but it was not heard publicly until 2003, when it surfaced on a retrospective collection entitled "The Best of 1963-78".
